Berndtia purpurea Hire (Kriiger, 1940), not a valid use of name. 



Diagnosis: Berndtia with mantle aperture not as long as width 

 of mantle; adhesive disk long and narrow; female 3-5 mm X 2-4 mm; 

 violet-blue beneath aperture, rest pinkish yellow; found in hving 

 intfertidal corals Lepastrea purpurea (Dana) and Psammocora pro- 

 jundaxiella Gardiner, from the Pacific Coast of southern Japan. 



The nature of the symbiotic association with the living coral colony 

 is an interesting problem. There seems to be a competition for space 

 with the barnacle crowding the polyps. The polyps form a partition 

 between themselves and the barnacle (Utinomi, 1957). 



Kruger (1940) referred to the name Berndtia purpurea without any 

 descriptive material. He based the name on a letter from Hiro, who 

 published a note on the new barnacle in 1937. Hiro has assumed the 

 name of Utinomi. The complete species description was published by 

 Utinomi in 1950. 



Utinomi has made a thorough study of this species, to which the 

 reader is referred (1950a, 1957, 1960, 1961, and 1967). He gave me a 

 few specimens, upon which the accompanying figure is based. 



Berndtia fossata, new species 



Figure 18 



Diagnosis: Berndtia with opercular lateral margins with fine teeth 

 each serrated into three to five points arranged in an arc. 



Etymology :/ossa (L.), a ditch, because it lives in a "little ditch" of 

 its own making, in addition to the host name. 



Distribution: One almost complete specimen and three partial 

 specimens in Psammocora fossata from Siassi (Low Island) , eastern 

 New Guinea. Coral from the Australian Museum G6678, thanks to 

 John Yaldwyn.
